Doc Text:	A flaw was found in FreeRDP-based clients. Affected versions of FreeRDP are vulnerable to an integer overflow and out-of-bounds write. This issue occurs when the sum of the `runLengthFactor` and `pixelIndex` values become large enough to overflow the uint32 type and bypass an error check when clearing residual data.

Description Zack Miele 2024-04-23 20:51:08 UTC

FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based clients using a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to integer overflow and out-of-bounds write. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, do not use `/gfx` options (e.g. deactivate with `/bpp:32` or `/rfx` as it is on by default).

Does this vulnerability affect a RHEL 7.9 system that only has freerdp-libs-2.1.1-5.el7_9.x86_64?
